Bandera Brown directional permeability

Interpretation

The current workflow predicts Bandera Brown with a quadratic-mean permeability error of 0.18% relative to the Table 1 experimental reference. This case should be interpreted together with the cross-sample summary in DRP-317 sandstone validation overview.
